Abstract (en)

[origin: EP3043136A1] Provided is a thermal diode 3 that can be used at room temperature and that easily transfers heat in a certain direction. The thermal diode 3 is formed of a first material 1 as a ceramic material exhibiting thermal conductivity that increases in a certain temperature range of -200°C or higher but 1000°C or lower and a second material 2 exhibiting the thermal conductivity that decreases in the temperature range, the first material 1 and the second material 2 being bonded together. The first material 1 has preferably a microstructure having a characteristic length L a of 1 nm to 10 µm.
